Analysis of Polycyclic Aromatic Hydrocarbon Derivatives by On-Line Coupled Packed-Capillary High-Performance Liquid Chromatography-High-Temperature Gas Chromatography

摘要

A packed-capillary high-performance liquid chromatograph (#mu#-HPLC) is coupled on-line to a high-temperature capillary gas chromatograph (HTGC) through a multiloop, nonsplit, in-column interface. Polycyclic aromatics and aliphatics of oils of residuum and extracts of residue in the petrochemical industry are analyzed using #mu#-HPLC-HTGC. Quantitative results are obtained and discussed with respect to frame structure and carbon number distribution.
